Actually that's pretty good. I don't see any reason to upgrade unless you actually have the money to do so. I game just fine with a similar speed, slightly less. I have Comcast too. Just need to get a different router, because the ones they use up here are horrible.

lol perhaps when i upgrade my pc and i feel a need for it, i game just fine but i wanted to see if i could be doing better by speeding up my connection but if u say its fine then i'll stick with the plan i have :P
